Kapp Lunar Flux™ - Soldering Flux for Aluminum

550°F- 800°F (288°C - 427°C)

Kapp Lunar Flux™ is a white paste for the high temperature soldering of Aluminum and Zinc die cast alloy. It is a reaction-type flux with 70% active ingredients dispersed in alcohol. Kapp Lunar Flux™ has considerable shelf life stability, as the suspending agents prevent separation and re-crystallization of the active ingredients. The performance of the paste in depositing Zinc on Aluminum and die cast surfaces is also consistent over time.
